Why Is My Wine Fizzy

is a beloved enjoyed by many around the world. Whether you're a casual wine drinker or a wine connoisseur, you may have come across a bottle of wine that has a fizzy or effervescent quality to it. This can be both surprising and confusing, as still wines are not typically expected to have bubbles like their counterparts. So, why is your wine fizzy? Let's explore the possible reasons behind this phenomenon.

Firstly, it's important to note that not all fizzy wine is bad or spoiled. In fact, some wines, particularly certain white wines, are intentionally made to be slightly effervescent. These wines, often referred to as “petillant” or “frizzante,” undergo a secondary fermentation process after bottling. This secondary fermentation occurs when the residual sugars in the wine interact with , producing carbon dioxide. The carbon dioxide gets trapped in the bottle, creating the bubbles or fizz.

However, if you have a bottle of wine that was not intended to be fizzy, then there may be other factors at play. One possibility is that the fermentation process was not properly controlled or stopped. During fermentation, yeast consumes sugar and converts it into and carbon dioxide. If the fermentation is not fully halted before bottling, residual sugars can continue to be fermented, resulting in the production of carbon dioxide and thus, fizziness in the wine.

Another reason for fizzy wine could be a re-fermentation in the bottle. This can occur if there are still dormant yeast cells present in the wine at the time of bottling. These yeast cells can become active again if conditions are favorable, such as a slight increase in temperature or the presence of additional sugars. The re-fermentation process can lead to the production of carbon dioxide, causing the wine to become fizzy.

Cloudiness in the wine can also be an indication of a secondary fermentation occurring. If you notice sediment or haziness in your wine, it could be a sign that fermentation is still ongoing. Similarly, a change in color, particularly a browning or oxidized appearance, can suggest that the wine has undergone some unwanted fermentation or oxidation processes.

When it comes to detecting whether a wine has gone bad or spoiled, there are a few other signs to look out for. Acetic acid scents, which resemble the smell of vinegar, can indicate the presence of acetic acid bacteria, which can spoil the wine. Additionally, oxidation smells, such as a nutty or -like aroma, can suggest that the wine has been exposed to too much oxygen, leading to a deterioration in quality. Reduction odors, on the other hand, can give the wine a sulfurous or rotten egg-like smell, indicating that the wine has not been properly protected from oxygen.

So, if you find yourself with a fizzy bottle of wine that was not intended to be effervescent, it may be a sign of incomplete fermentation or re-fermentation in the bottle. However, it's worth noting that a small amount of fizz in your wine is generally harmless and does not necessarily mean the wine is spoiled or undrinkable.

The fizzy nature of wine can be attributed to various factors, including intentional secondary fermentation, incomplete fermentation, or re-fermentation in the bottle. While fizzy wine may not always be desirable, it doesn't necessarily indicate that the wine is bad. As with any wine, it's important to trust your senses and look out for other signs of spoilage or deterioration before determining whether the wine is still enjoyable to drink. Cheers!

Is It OK To Drink Fizzy Wine?

Fizzy wine, also known as sparkling wine or effervescent wine, is indeed safe to drink and can be quite enjoyable for many people. Here are some key points to consider:

1. Second Fermentation: Fizzy wine undergoes a second fermentation process after it has been bottled. This process creates carbon dioxide gas, which is responsible for the bubbles and fizziness in the wine.

2. Different Varieties: There are various types of fizzy wines available, each with its own unique characteristics. Some popular examples include , Prosecco, Cava, and sparkling wines from different regions around the world.

3. Taste and Experience: Fizzy wines often have a refreshing and lively taste, making them a popular choice for celebrations and special occasions. The bubbles can enhance the overall drinking experience by adding a sense of effervescence and lightness to the wine.

4. Food Pairings: Fizzy wines can be versatile when it comes to food pairings. They can complement a wide range of dishes, including seafood, appetizers, cheeses, and desserts. Some people also enjoy fizzy wines on their own as an aperitif.

5. Serving Temperature: It is important to serve fizzy wine at the proper temperature to fully appreciate its flavors and bubbles. Generally, sparkling wines are best served chilled, around 40-50°F (4-10°C).

6. Storage and Opening: Like any other wine, fizzy wine should be stored properly to maintain its quality. It is recommended to store it in a cool, dark place and avoid exposure to excessive heat or sunlight. When opening a bottle of fizzy wine, it is advisable to do it slowly and carefully to prevent excessive foam or spillage.

7. Personal Preference: Ultimately, whether it is okay to drink fizzy wine depends on personal preference. Some people may enjoy the bubbly nature and unique characteristics of sparkling wines, while others may prefer still wines. It is always good to explore different types of wines and discover what suits your taste buds.

Fizzy wine is safe to drink and can provide a delightful and effervescent experience. It offers a range of flavors, pairings, and serving options. However, it is essential to store and open it properly, and ultimately, the decision to drink fizzy wine or not depends on personal preference.


Wine is a complex and delicate beverage that can undergo various changes over time. While a little bit of fizz in a may not necessarily be harmful, it indicates that the fermentation process did not fully stop when the wine was bottled. This can result in an effervescent or fizzy texture, which is not desirable in still wines.

To determine if a wine has gone bad, there are several signs to look out for. Cloudiness, a change in color towards browning, the development of bubbles, acetic acid scents, and oxidation or reduction odors are all indicators that the wine may have spoiled.

If a wine does exhibit signs of being fizzy or effervescent when it shouldn't be, a winemaker may choose to decant the bottles and wait until the carbon dioxide production stops. Once the wine has clarified, it can be sterile-filtered and bottled again to eliminate any potential issues.

It is important to understand the characteristics of wine and how it can change over time. By being aware of the signs of spoilage, wine enthusiasts can ensure that they are enjoying the best possible experience when indulging in their favorite vintages.
